Manzanita Lake Loop, the easy one
A 1.7 mile flat loop around Manzanita Lake, near the northwest entrance at Loomis Plaza. It suits a family with young kids.
Bumpass Hell, the one most people mean
3 miles round trip, about 90 minutes, from a trailhead at roughly 8,200 feet. The trail drops 300 feet into the park’s largest hydrothermal area.
Lassen Peak, the whole day
5 miles round trip, 1,957 feet of climb, 4 to 5 hours. Weather changes fast at 10,457 feet and afternoon thunderstorms are common in summer.
When the trailheads open
All three need the park highway. Dates are in our road opening dates post, and fees are in our Lassen guide.
